Was your engine builder Micheal’s in Macedonia, Ohio? I have a build slot with Superformance in December for. Wide body Heritage Mark I, and will end up with a twin to your car. It is my second GT40. I own GT40/P 2047, that Shelby built as a commemorative Mk II that matches Gurney/Grant 1047 that set pole at LeMans. If your builder is Michael’s, they are located just a couple miles from my summer home in Ohio.
